Describe the polarity of the molecule below and predict the shape of the molecule by looking at its Lewis dot structure.
1 answer:
Answer:
Polar and bent
Explanation:
It looks like you are trying to find the polarity of H-O-H.
Its Lewis structure is shown in the first diagram below.
It has two lone pairs and two bonding pairs, so it is an AX₂E₂ molecule and its molecular shape is bent, as in the second diagram.
O is much more electronegative than H, so the O-H bond is highly polar. The O atom is at the negative end, and the H atom is at the positive end.
The centre of negative charge is on the O atom, and the centre of negative charge is halfway between the two H atoms, so the molecule has a net dipole pointing "up" in the picture.
Thus, H-O-H has polar bonds and is a polar molecule.

Explanation:
Transfer of mass A into stagnant film B depends on the availability of driving force.
Whereas driving force is the pressure difference at the surface of A and the bulk.
As,
Therefore, putting the given values into the above formula as follows.
=
= 0.132
Thus, we can conclude that the flux of A from a surface into a mixture of A and B is 0.132
